    R7 240 can't display 60Hz @ 4K resolution only 30Hz

    bschelew

      Have installed the latest drivers for the R7 200 series and can only get 30Hz using 3840x2160 resolution through HDMI 2.0 port. (Monitor supports 3840x2160 @ 60Hz.) No Display Port on my particular R7 240 card from Yeston.

       

      Do I need a special HDMI cable or is there something wrong with my graphics card?

      FYI: Have a second display 1920x1080 @ 60Hz running fine through DVI cable.

          First HDMI 1.4 only support 4k@30 hz according to Wikipedia : HDMI - Wikipedia

          Version 1.4[edit]

          HDMI 1.4 was released on May 28, 2009, and the first HDMI 1.4 products were available in the second half of 2009.[62][98] HDMI 1.4 added support for 4096×2160 at 24 Hz, 3840×2160 at 24, 25, and 30 Hz, and 1920×1080 at 120 Hz.[99](§6.3.2) It also added an HDMI Ethernet Channel (HEC) that accommodates a 100 Mbit/s Ethernet connection between the two HDMI connected devices so they can share an Internet connection,[43] introduced an audio return channel (ARC),[41] 3D Over HDMI, a new Micro HDMI Connector, an expanded set of color spaces with the addition of sYCC601, Adobe RGB and Adobe YCC601, and an Automotive Connection System.[62][100][101][102][103] HDMI 1.4 defined several stereoscopic 3D formats including field alternative (interlaced), frame packing (a full resolution top-bottom format), line alternative full, side-by-side half, side-by-side full, 2D + depth, and 2D + depth + graphics + graphics depth (WOWvx).[61][104][105] HDMI 1.4 requires that 3D displays implement the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24.[105] High Speed HDMI cables as defined in HDMI 1.3 work with all HDMI 1.4 features except for the HDMI Ethernet Channel, which requires the new High Speed HDMI Cable with Ethernet defined in HDMI 1.4.[61][104][105]

          HDMI 1.4a was released on March 4, 2010, and added two mandatory 3D formats for broadcast content, which was deferred with HDMI 1.4 pending the direction of the 3D broadcast market.[106][107] HDMI 1.4a has defined mandatory 3D formats for broadcast, game, and movie content.[106] HDMI 1.4a requires that 3D displays implement the frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24, side-by-side horizontal at either 1080i50 or 1080i60, and top-and-bottom at either 720p50 and 1080p24 or 720p60 and 1080p24.[107]

          HDMI 1.4b was released on October 11, 2011,[108] containing only minor clarifications to the 1.4a document. HDMI 1.4b is the last version of the standard that HDMI Licensing, LLC is responsible for. All future versions of the HDMI Specification were produced by the HDMI Forum, created on October 25, 2011.[35][109]

           

          The MSI r7 240 (2 gbyte) GPU card only has HDMI 1.4a. You need HDMI 2.0 for 4k@60 HZ.

              The Sapphire R7 240 also has HDMI 1.4a : B&H Photo Video

              According to AMD Support on the R7 240 it will support 4k Resolutions @ 60 hz using MST or SST enabled Monitor only. : https://www.amd.com/en-us/products/graphics/desktop/r7

                  elstaci,

                   

                  Thanks for the indepth info. My takeaway is this:

                   

                  My Philips monitor has an HDMI 2.0 port which the specs in their manual

                  state does support 4K@60Hz. (No mention of SST or MST).

                  An official  AMD produced r7 240 does support 4K60Hz according to your post

                  but other manufacturers that licence and assemble the AMD graphics card

                  under their own brand (such as the Sapphire r7 240) may only have the HDMI

                  1.4 port and thus only output 4K@30Hz.

                   

                  On the site where I bought the Yeston card (the manufacturer of my

                  particular AMD r7 240 card...

                  https://www.gearbest.com/graphics-video-cards/pp_734473.html) it does not

                  specify whether the HDMI port supports the 60Hz. Since it is silent on

                  that, I suspect that it does not. Too bad. I just figured that ALL AMD r7

                  240's would have the same specs (i.e., as listed on the AMD site) and 3rd

                  party manufacturers wouldn't substitute in inferior parts. Lesson learned.

                   

                  Thanks again for the clarification.
